Abstract (en)
[origin: WO8900260A1] In a process and device for cleaning lubricating oil in a gearbox (1) with pump-lubricated bearings (12, 52, 15) and gears (13, 14, a lubricant pump (2) conveys lubricating oil from a container (21), primarily from the pump of the gearbox (1). In a shaft of the gearbox, primarily the input shaft (4), the lubricant channel expands into a rotation chamber (3), so that the flow rate is markedly reduced and the rotary movement of the outer surface (31) of this chamber is imparted to the lubricating oil. The dirt particles are centrifuged onto the outer surface (31, 34) on which they form a strongly adherent film. The cleaned lubricating oil is directed to the centre (32) of the rotation chamber (3) and conveyed in a known manner through a bore hole (53) in the main shaft (5) to the consumers, e.g. the bearings (12, 15, 52).
